http://www.youtube.com/watch?v=5VcSwejU2D0 A video from Houston's mayor's office details how to survive a mass shooting situation
I stumbled on a pic of what the maniac in colorado supposedly wore...a lot of military/SWAT grade firearms and armor... There's no way a gun that granny's packing would incapacitate him in a dark movie theatre. It might feel like an obligation to jump in and play the hero, but the video's instructions for when to fight is the generally safer move. Secure yourself, know the situation, then commit to taking the wacko down.
